Most of the juvenile femoral head necrosis is caused by congenital acetabular dysplasia, trauma or use of large doses of hormones, etc. General treatment, medication, physical therapy and surgery can be chosen for treatment. 1. General treatment: patients should avoid weight-bearing on the affected limbs, and can relieve the pressure on the hip joint by holding the crutches or resting in bed, and those who are overweight should actively reduce their weight to minimize the process of femoral head necrosis. 2. Medication: non-steroidal anti-inflammatory drugs, such as naproxen and ibuprofen, can be chosen to alleviate the pain symptoms, and low molecular heparin and other anticoagulant drugs can also be chosen. 3. Physiotherapy: Physiotherapy such as hyperbaric oxygen therapy, high-frequency electromagnetic field therapy and extracorporeal shock wave therapy can be chosen to repair the necrotic lesions and promote new bone formation. 4. Surgery: If conservative treatment is ineffective, surgery can be chosen, and the main surgical methods include core decompression, autologous bone grafting with blood transport, artificial hip replacement and osteotomy. Patients with femoral head necrosis should go to the hospital in time, and actively carry out standardized treatment according to their conditions. All of the above drugs should be used according to the doctor’s prescription.
